  /dev/cpu/*/msr. A local root user with all capabilities dropped could
  exploit this flaw to execute code with full root capabilities.
  (CVE-2013-0268)

  A flaw was discovered in the Linux kernels handling of memory ranges with
  PROT_NONE when transparent hugepages are in use. An unprivileged local user
  could exploit this flaw to cause a denial of service (crash the system).
  (CVE-2013-0309)

  A flaw was discovered on the Linux kernel's VFAT filesystem driver when a
  disk is mounted with the utf8 option (this is the default on Ubuntu). On a
  system where disks/images can be auto-mounted or a FAT filesystem is
  mounted an unprivileged user can exploit the flaw to gain root privileges.
  (CVE-2013-1773)";
